Html5 - radio buttons

Hi i don’t really know why my code is not right i double checked the spelling and it says that " Each of your radio button elements should be added within the form tag."

  **Your code so far**

<h2>CatPhotoApp</h2>
<main>
<p>Click here to view more <a href="#">cat photos</a>.</p>

<a href="#"><img src="https://bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back."></a>
